This feature article provides an overview of the advances in APPJ technology and its application to solar cells and batteries. The ultrafast APPJ sintering of nanoporous oxides and 3D reduced graphene oxide nanosheets with accompanying optical emission spectroscopy analyses are described in detail. The applications of these nanoporous materials to photoanodes and counter electrodes of dye-sensitized solar cells are described. An ultrashort treatment (1 min) on graphite felt electrodes of flow batteries also significantly improves the energy efficiency. © 2015 by the authors.Atmospheric pressure plasma; Atmospheric pressure plasma jet; Dye-sensitized solar cells; Graphene; Graphite felts; Metal oxides; Nanoporous materials; Optical emission spectroscopy; Redox battery; Reduced graphene oxidesjournal article10.3390/coatings50100262-s2.0-84943274187
